Is there any software by which someone will be able to retrieve the data. Any kind of information will help. Sometimes some people ask these questions and I am at a loss of words. If any software can recover it please let me know.

Anyone? Like the NSA?

Yes. If you're trying to keep secrets from people, you shouldn't keep

them on computers. There are ways your disk image could be seized and

the temp files used in the PACK and then deleted could be recovered

and read. Browse around in the temp directories. But that's not all

that likely.

If you're keeping your data on a network storage device, it may make

backups. If you're using Windows, it may store your files in a restore

point.

Realize that anything entered into a computer might show up at the

worst possible moment. You regularly hear about scandals where someone

thought the email they deleted was gone forever. That's naive.

Do you make backups? Don't forget to shred them. And burn the bits.

There are ways to prevent, or mitigate all of these risks, but you

need to be careful about your answers there. If it's the company's

price list, which all their customers already know, perhaps a PACK is

sufficient. But if it's information that could cost peoples their

lives or livelihoods

> Currently what I am telling them that's its not possible & that its something like you have an excel sheet of say 100 rows. You then delete 20 rows and save it. After saving whether it possible to recover the deleted rows??

Well, that's pretty unlikely. Sometimes Excel stores stuff in its

spare spaces. I still wouldn't keep my secrets on it.
